The verdict
What the panel makes of it.
The Amazfit GTR 4 ranks sixth among Apple Watch alternatives, earning strong buyer satisfaction (4.7/5) for its fourteen-day battery life, premium aluminium build, and bright AMOLED display, but reviewers and owners alike flag unreliable heart-rate tracking during exercise as a serious limitation for athletes. Best suited to casual users prioritising design and longevity over workout precision.

AI summary of 5 reviews · as of May 2026
A well-built, attractive smartwatch with excellent battery life and fluid software that stumbles badly on heart-rate accuracy during exercise.
What they praise
- Battery life extends to fourteen days in normal use, far outlasting Samsung and Apple competitors
- AMOLED display is bright, sharp, and readable outdoors with good contrast and vivid colours
- Aluminium build feels premium yet remains light at thirty-four grams with a comfortable, skinny profile
- ZeppOS 2.0 interface is smooth and responsive with minimal lag or stutter when navigating menus
- Five atmospheres water resistance and durable construction with no visible scratches after weeks of use
What they knock
- Heart-rate tracking is unreliable during workouts, often detecting half the actual rate or missing peaks entirely
- Notifications arrive late frequently, repeating the same flaw from previous generations
- App ecosystem remains limited compared to Wear OS, with no Google Maps or complex navigation apps
- Heart-rate accuracy appears highly sensitive to exact wrist position, producing hit-or-miss results
In their own words
“if you fancy yourself pretty much all of the features that you'd get in a Samsung or an apple Smartwatch but with the added bonus of superior battery life”
— Tech Spurt
“the touch response is very good and there is no lag in the menu. And I didn't see even a minor stutter or lag while going through the pages.”
— Gadget Gig
“their heart rate tracking and sleep tracking have been amongst the worst out there”

What owners single out
Buyers' weakest aspect—heart-rate tracking—directly overlaps video reviewers' finding that it's unreliable during workouts and highly sensitive to wrist position.
In their words
“I bought the GTR 4 because I was really frustrated by the poor GPS tracking on the FitBit Charge 6. Admittedly, this is a much larger device. But for around the same price, it has so many features and the GPS Dual-band positioning is both reliable and accurate. I've found that it is also easy and intuitive to use. In my eyes the GTR 4 is also much better looking as an all-day wrist-watch. It is a ”

“Great watch, heart rate is a little off when exercising. My big issue is the crown stopped working after about a year and 4 months. It won't pop back out after pushing in and it makes the watch difficult / impossible to use. I want to buy a Balance, but I am worried that the same thing will happen to that since the design is very much the same.”

For you if
Look elsewhere if
You love a smartwatch that delights you with its look, feel, and sensory experience beyond raw specs.
Reviewers praise the premium aluminium feel, light 34g profile, bright AMOLED display with vivid colours, and attractive round-dial design—clear aesthetic passion.
You need a proven, low-risk smartwatch with broad consensus and a trusted brand behind it.
1108 ratings with 4.7/5 average, mature ZeppOS 2.0, durable build, and Amazfit's established track record make this a settled, trustworthy choice.
You value a prestigious brand and refined design that signals taste and quality.
Amazfit is an established maker; stainless steel, AMOLED, premium feel at 34g, and attractive round dial align with connoisseur expectations, though not a flagship of Apple or Samsung.
You want a smartwatch that works straight out of the box without fiddling or complex setup.
ZeppOS 2.0 is praised for smooth, responsive navigation with minimal lag; no mention of setup friction or configuration burden in reviews.
You demand a smartwatch with no meaningful flaws and best-in-class performance across the board.
High rating (4.7/5) and strong build/design/battery, but heart-rate accuracy during exercise is a clear, documented weakness that disqualifies it from top-tier perfection.
You want a smartwatch that won't break the bank but delivers solid everyday features.
At ~$555, it's mid-to-premium priced; cheaper rivals like Charge 6 (~$138–160) cover basics without the cost, making the GTR 4's value proposition weaker for budget-conscious buyers. Consider Charge 6.
